When connecting 10/100 ports to devices such as servers, workstations, and routers, you can use a two 
or four twisted-pair straight-through cable wired for 10BASE-T and 100BASE-TX.

straight-through cable schematics.

When connecting the ports to other devices, such as switches or repeaters, you can use a two or four 
twisted-pair crossover cable.

If auto-MDIX is disabled, use a straight-through cable to connect ports when only one port is labeled 
with an X. Use a crossover cable to connect ports when both ports are labeled with an X or when both 
ports are not labeled with an X.

You can use Category 3, 4, or 5 cabling when connecting to 10BASE-T-compatible devices. You must 
use Category 5 (or higher) cabling when connecting to 100BASE-TX-compatible devices.

You can use the mdix auto interface configuration command in the CLI to enable the automatic 
medium-dependent interface crossover (auto-MDIX) feature. When the auto-MDIX feature is enabled, 
the switch detects the required cable type for copper Ethernet connections and configures the interfaces 
accordingly. Therefore, you can use either a crossover or a straight-through cable for connections to a 
copper 10/100, 10/100/1000, or 1000BASE-T SFP module port on the switch, regardless of the type of 
device on the other end of the connection.
